Good morning friends. Flappy's quest for extreme learning efficiency has led us to build the 'Kittens Virtual Machine' (KVM) framework, which launches a megakernel that acts as a persistent runtime and exposes its own instruction-based programming model. The KVM (a) provides unprecedented control and visibility over the hardware (something we've been extensively utilizing to accelerate our internal research), exposing a completely new kind of systems–training co-design space, (b) reaches vastly SoTA speeds without hand-tuned kernels, and (c) tremendously increases GPU utilization by co-packing multiple independent workloads into the same kernel.
